External Anchoring Configurations for Modular Gastrointestinal Prostheses
First Claim
1. A gastrointestinal implant system for treating metabolic disorders such as diabetes and obesity, the system comprising:
- a tubular implant adapted for placement within at least a portion of the duodenum, the tubular implant having a securing feature; and
an external band configured for implantation around at least one of a pylorus, and a duodenum, the external band having a coupling feature for removably engaging and coupling with the securing feature of the internal tubular implant, without penetrating the duodenum or pylorus, such that the therapeutic implant resists migration within the gastrointestinal tract, and the external band having an implanted inner diameter generally equal to a corresponding outer diameter of the duodenum or pylorus;
wherein the securing feature and coupling feature are configured such that the tubular implant is releasably coupled to the external band to facilitate removal of the tubular implant.

Abstract
Components may be used separately or in combination to create anchoring systems for intra-luminal implants for the treatment of metabolic disorders such as obesity and diabetes. Various systems include an external component adapted for deployment around a portion of the gastrointestinal tract (e.g., the duodenum) and an internal component adapted for implantation within the gastrointestinal tract. Various systems use anchoring means that are based on mechanical interference, elasticity, spring force, shape memory transformation, magnetic attraction, repulsion and/or levitation. Various embodiments rely on longitudinal anchoring of the implants with minimal force against tissue.

17. A method of treating metabolic conditions such as diabetes and obesity, the method comprising:
-
placing an external implant around at least a portion of the duodenum, the external implant having a docking feature and the external implant having an inner diameter generally equal to an outer diameter of the corresponding portion of the esophagus; implanting, using a minimally-invasive technique, an internal tubular implant having a securing feature to a location within the duodenum corresponding to the location of the external implant; and causing the securing feature to removably couple with the docking feature without penetrating the duodenum. - View Dependent Claims (18, 19, 20)
